Back in February, together with Richard Treves at the University of Southampton, I submitted an application to the Google’s Faculty Research Award program for a grant to investigate Google Earth Tours in education. We were successful in getting a grant worth $86,883 USD. The project builds on […]
I’ve created a new html template for the GMapCreator that uses Google’s API v3. In addition to not requiring the API key which is locked to the URL, this also means that you can take advantage of Google’s new styled maps base layers and Fusion table overlays. The following map shows UK geology as the […]

As the Windows native version of the Java Advanced Imaging (JAI) project that the GMapCreator depends on is 32 bit only, I needed to use the pure Java version of JAI. It’s not immediately […]

Continue reading »I’ve been looking at the Weather Underground API (http://wiki.wunderground.com/index.php/API_-_XML) which gives access to the observation stations and the data they are collecting. The API uses simple commands to query for a list of stations, for example: http://api.wunderground.com/auto/wui/geo/GeoLookupXML/index.xml?query=london,united+kingdom Using C# and .net, this is accomplished as follows: WebRequest request = WebRequest.Create(string.Format(GeoLookupXML, @”london,united+kingdom”)); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); XmlDocument […]

The Science Communication Conference last week afforded me and a panel of podcasting peers the opportunity to talk about science podcasting – but I feel that there were a lot of key things I didn’t really get across. I thought … Continue reading →
Yesterday, with a host of podcast luminaries, I ran a discussion session on science podcasting at the British Science Association Science Communication Conference – or a podchat, as my brain insisted on referring to it for reasons of brevity. The … Continue reading →

The rational behind the comparison is that Meridian 2 represents a generalised geographic dataset that is widely use in national scale spatial analysis. At the time that the study started, […]
Dr Muki Haklay,UCL CEGE, has been carrying out some quantitative research into OpenStreetMap’s coverage in the UK, comparing road lengths in each square kilometre, with those in a definitive national dataset, Ordnance Survey Meridian 2. He’s updated his findings every … Continue reading →
